support 2 is mounted adjacent one c'o'rner therecf.v

This support carries a yoke member 3 having arms 4 a'nd 5, by which theroll, indicated generally by the numeral 6, is carried. It will be notedthat the yoke is .closely adjacent the longitudinal extent of the roll6, and that the armsv 4 and 5 support'- the rollin sucha manner that theends of the latter are substantially entirely open, the left-handendbeing free on allsides, and the fright-hand end being free on its topand side. I

that a tube or cylinder 22 is provided. rranged interiorly of the tubeare three partition plates 23, 24 and 25.' I'he plate 23 holds the rearbear# Spiders l and 8, of skeleton form, are located in the rolladjacent to the respective ends thereof and will hereinafter bedescribed in detail.

Also mounted on the base 1, preferably in the :corner diagonallyopposite from theA support 2, is a second support or pedestal 9, onwhich is carried a shoe 10. `It"will be. noted that the shoe issupported at a' point intermediate the ends, preferably at pointsubstantially midway therebe- `tween. It will be further noted that thesupports 2 and 9 between .them forml a Ll-member, of

which the base 1 is the' head or yoke, whereby the ends of theironer areleft substantially unobstructed for Y the passage of large pieces. Byhaving the supports staggered along the ylength of the base with-respectto each other, the overall widthof the base is materially diminished.

In either the over feed or under feed type, it

i is the forward member, relatively to an operator,

' ne'ath its end, and the rearward member is supe` apertures 13, wherebyVentilating channels areprovided, extending throughout the length of thewhich is supported substantially at .and underported substantiallyintermediate its length..v By this construction, the desired economy inthe material-for the base is achieved,-while at the same' Atime there-issubstantially no obstruction, to the rea'dy insertion of the material tobe ironed over any part of the entire length of the ironer.

VAs more clearly shown'in Figs. 1 and 3-5, the roll 6 comprises atubular member 11, mounted on and supported adjacent its ends by thehereinbefore 'mentioned spacers or spiders 7 and 8. lThe' member 11 maybe secured 'thereto .as by screws 412, 12 in such manner that the member1 1 is iixed to'and rotates with the spiders '7 and 8. The spidersareshown as having. a plurality of roll..

Mounted on and closely adhering to the member 11 :isa roll'padding 14.--A single piece of Fig. 29 is an elevation, partly in section, ofthellhair felt, jute felt', or the like is placed around the roll in suchmanner that the edges of the padding meet evenly. The pad is then glued'or vsecured by material such. 'as cement to the surface of the member11, whereby the .material is solidly and securely fixed to the roll.AIf.intermediatecoverings are employed, these are in turn secured tethev roll. surface.

` Located substantially centrally rthrough. the end portion of lthe tube11, for a small portion lof its extent are stubshafts 15,.15. Theseshafts are preferably. adapted for a slight displacement in the arms 4and 5 as'will be hereinafter more fully described. Pivotally securedeither directly or indirectly to the arms 4 and 5 in any suitablemanner, are crank arms 16 and 17, or links such as 160 and 154 in Fig.30 which carry the stubshafts and l5', respectively, adjacent their' anydesirable manner, and while the roll may be fixed -in space, and theshoemay be movable towards and away from the roll, I use the reactionthrusts of the motor, preferably mounted internal- .ly of the. ro1l,'tomove the roll towards and away 'from the shoe, which latter inthepreferred in- Referring more.

stance, is' fixedV Von the base. particularly to Figs. 1-5 inclusive, itwill be seen ing of the motor 26; the plate 24 separates the motorchamber from the gear box, which preferably is filled 'with lubricant,and also holds the forward motor'bearing and contains sockets f or thegear bearings; while the plate holds the remainder of the gear bearingsfThe stub'shaft 15 'is fixed in plate 24, and extends through plate 25. A

In my preferred construction'an economy of 30% or more in the cost ofthe motor is obtained over prior constructions ;l approximately threeand a half (3l/2) to five (5) pounds. is saved in the gross weight; analmost 'self-'aligning construction is. obtained, la. ltube always.being straight -and true; and a constructionis'produced which is verydiftlcult tov get out of line.` Further, no machining is required withthe tubular construe At the left-hand side of tion since its interioran'd ends aretrued as soon as the partition 24 is forced to the center,the surface of the tube being smooth. A still further advantage of theforegoing construction is that direct ventilation is provided throughoutthe length'of the roll, through the openings 13 inthe spiders Tand 8.

In order to insure proper ventilation of the motor 26, afan 146 ismounted on the shaft 147 thereof. A baille plate 23', an'opening 148, ismounted within the tubular member 22, and rearwardly of an opening149therein. By

.this -construction, air is sucked in bythe fan, in 'the direction ofthe arrows,l from the interior of the roll 11, through `the'open-ings149,'and 148,A through' the motor 26, and outwardly through the spacer23. 'I'he fan 146, -by increasing 'the- `incoming quantity of air,improves the ventila tionof4 the roll` .as a wholeasv well as that ofthe motor.

Current is supplied to the motor 26` by means of leads 27 and 28 passingthrough a conduit 29 vand 24, respectively, so that the eccentric arms16 and 17, when properly actuated, will swingthe stubshafts and 15'Vtowards the shoe 10. As shown-in Fig. 1' the slot in-the'arm 4 and inwhich the shaft 15 rides is concealed from view, while that in the arm5, for the shaft 15', can be arranged either visible or invisible fromthe exterior, at the option of the manufacturer. A This slot is hereshown at 34 in Fig. 7: Rotation in the counter-clockwise direction ofthe motor and consequent rotation of the clutch 47 in the oppositedirection causes the rotation ofthe roll 6- in the same direction as theclutch47.

When energized, the motor shaft 147 rotates, carrying with it thedriving pinion 35 which in turn meshes with a gear 36 fixed to a shaft37, mounted at 38 and 39 in suitable bearings in the partitions 24 and25 respectively, Through a pinion 40 fixed onthe gear 36, themodifiedrotatation of the motor is transmitted to the gea'r 41, carried on theshaft 42 (Fig. 5), which is also journaled or otherwise-mounted in thepartition plates 24, 25. A pinion 43 is secured to the shaft 42 and inturn drives the spur gear 44. This gear translates the rotative force ofthe motor 26, at reduced speed to the sleeve 45, fitting loosely aboutthe shaft 15', and spaced by bushingsr46, 46, and which sleeve carriesat its other end a clutch plate 47 having a plurality of ratchet teeth48. At such times as the clutch plate 47 is disengaged from itscooperating clutch members, the motor rotates without affecting oractuating the roll.

Suitable means are provided for cooperation with the clutch member, andwhile these may take any desired form, they'preferably compriseelongated bearings 49, 49 in the spacer 8, through which bearings thepawl-arms 50, 51 are journaled. A cross member 52preferably-interconnects the pawl-arms at their outer extremities, andin its present exemplification is shown 'as having an `the peripherythereof.

annular flange 53, on its inner face. This flange is adapted tocooperate with a corresponding outwardly extending hub 54 on the outerfaceof the spacer 8; and the two elements retain between them a vspring55,'-preferably helical, which tends -to maintain the cooperating clutchelements in their disengaged positions- ,i

It is essential thatthe roll 6 be'prevented or retarded from rotatingduring such time as it is being moved from its normalposition of restinto engagement with the shoe 10, in order that the rotative force ofthe motor 26 may be utilized to effect the bodily displacement of theroll. To this end, the spacer plate 8 is preferably provided with aplurality of radial teeth 56, and these are shown in Figs. 1 and 3 asbeing arranged about Cooperating with the teeth 56 is a suitable pawlorcam member 57, shown in Figs. 1, 2 and 21 as beingsecured in anysuitable manner as by rivets or the like 58 v to a pawl-plate 59. Thislatter is' shown as termiwhich` willfbe/ hereinafter more fullydescribed. The pawl-plate is adapted for rocking motion about the shaft62 as an axis, and carries with it at such times the pawl and cam member57.

In the normal action ofthe device, the switch 31, of Figs. 6 and-7 isproperly actuated to effect heating of the-shoe and the rotation of themotor.

is initiated whenever the device is connected to the electrical outlet.A cam 64 on the cam shaft 62, both of which members will be more fullydescribed hereinafter, is operated in order to engage the ratchet teeth48 on the clutch plate 47 by means of the pawls and 51. 'Ihe motor. 26 II is then interlocked with the roll 6, by the engagement of the cam orpawl 57 with the'cooperating teeth 56, whereby the arms 16 and 17 arerotated in-their bearings, to bring the roll into contact with the shoe.

As shown in the present instance, suitable means such as a coiled`spring 65 is employed to cause the normal interengagement of theelements 56 and 57. The member 17 carries a cam arm 68, so that duringthe rotationof the portion 67 of the eccentric 17, the cam arm' 68 isrotated therewith. As a result of such rotation, the latter engagesunderneath an outwardly inclined projection 69 -of the cam orpawl 57.Continuation of the movement of the portion 67 of the eccentric 17causes the cam arm 68 to ridestill further along the under surface ofthe projection l69. This causes the pawl-plate 59 to rock about itsbearing 61, 61 andto release the cam 57 from its engagement 'with theteeth 56. By this action the roll is released and is free to rotate inits bearing against the face of the shoe l0. It will be readilyunderstood that the time factors ofthe several elements are socorrelated that the roll 6 will be released for rotation approximatelyat the moment when it comes into operating position adjacent the shoe.

Referring now more particularly to the construction of the cam 64, itwill be seen that the cam is carried on the shaft 62, which-latter isjournaled in bearings 70 and 7l, shown as projecting inwardly from thearm 5. Rotation of the cam 64, fixed to the shaft 62, causes movement ofthe pressure plate 72, carrying with it the cross member 52 and pawls 50and 51,'against ner, as by insertion through an eye of the lug,

the connecting rod being retained in place by means of the cotterlpn 76.The connecting rod 75 extends from the end of the roll down into theinterior of roll support 2, through an opening 77 arranged therein,where it engages in any sultable manner a .cranked projection 78 on asleeve 79 journaled in any suitable manner in the interior of rollsupport 2 as by means o`f suitable bearings 80. The hollow interior ofthe sleeve 79 is preferably for at least a portion of its extent, ofpolygonal form as 4at 83 whereby it is adapted to receive an actuatinglever 81. This construction is more fully illustrated in Figs. 2,and 6-9inclusive. In Figs. 6-7 the lever 81 is shown as ending in an'enlargedportion 82 suitably arranged for actuation by the knee of the operator.Should the ironer be placed on a table, the operator sity ting adjacentthereto on a chair or stool, it is i necessary merely that he turn onthe switch 31 by manual operation, after which the movement of the cam64 in Fig. l can be. controlled entirely by sidewise Amovement of theknee against the member 82. In this manner. the operators hands are leftsubstantially entirely 'free for the operations necessary to control the`materialtobe pressed in its passage through the ironer.

The machine is adaptable not only for use 'with a knee vactuated vmeanssuch Aas82,'but because of the polygonal socket 83, previously referredto, as illustrated in Fig. 2, the shaft 81 may be withdrawn and asuitable link 811be inserted inv its stead.4 A connecting link variablein length to suit tables of varying height operably associates the link8l with a lfoot treadle 85, which is shown as having a pivot point 86 ofany suitable form,

so that movement of the foot by 'an operator standing adjacent themachine may be translated to the roll 6 of the ironer to cause theproper l actuation thereof. If desired a chain-84 may be inserted inlieuof the link above referred to, which chain is adapted for insertionthrough an eye-85 in the foot treadle 85, after which -it may beconnected back'on itself in any adjusted position by'a hook member 84',terminating the free end of the chain, and engaging with a desired onelof the links thereof. By this arrangement, the

connecting means may be varied in lengthin'orde r to properly locate thefoot mechanism in operable position, regardless of the height from thefloor of the table surface on which the ironer-is Referring te Fig. 16lit may' be 'noted that the base lhas a portion 'substantiallyright-angular in form. At 88 the support or pedestal 121 v. (see Fig.12) for-the shoe 10 is mounted', while -at 89 placeis made for thecorresponding sup'- port or pedestal y2"of the roll 6 in the case of,the

under feed Vtype of ironer, while in the case of the over feed ironerthe support for the roll 2 is mounted at 88.' In this last-mentionedinstance -place is made at 89 for the 'corresponding support 9 for theover: feed shoe 10. Inthis connection compare Figs.. 6 and 'IA withFigs. 12 and 13. It is the portion 89 with which we are now particuylarly interested. `v As shown, lugs 90, 90 are pro- -vided in the formof bearings, and journaled ltherein by suitable means such as a pin 91(see Fig. 22) is the support or pedestal 2. This construction permits ofa slight pivotal movement of the rollv towards and'away from the shoe,by a .entame means es hereinefter described.' In the presentlconstruction such 'means comprise a threaded lug 92 vin which isthreaded a fllisterhead bolt 93 (see Fig. 22). Thisbolt extends looselythrough a hub 94. of a portion 95 of the bed lof the `base member, whichlatter carries cam surfaces 96 on its underside. Also'carried on the Ibolt 93, between the underside ofthe portion 95 and the head of thebolt; is the end portion 97 of ,acam lever 98. This cam lever is moreclearly "illustrated in Fig. 25. 'and'jis shown as having an inclinedcam surface 99 adaptedfor cooperation with the cam surface 96 of themember 95. The

leve'j98 has an upwardly extending portion 100 which extendsoutwardlytothe exterior through 'a slot 101.provided in the base 1. Ahandle por `tion 102 'permits manualactuation of the cam member in suchmanner that the distance be-' tween the hub 94 and the' member' 92 maybe diminished against the tension of a helical spring 103,'thus causingmovement of the roll about its Aaxis`91 away from the shoe 10. .Manualadjustment of thebolt' 93 in member92: permits the distance between theshoe'and the roll to be ad- -,iusted to compensate for any packing. ofthe tol be ironed. The useofl the lever 98 permits the roll 'to beremoved from the shoe in forder to prevent scorching -of the surfaces ofthe several parts. especially while the machine is cooling after theironing period is past.

While the constructions of the base 1, as illustrated in Fig. 16, hasbeen described with particular reference to the under feed constructionof Figs. 22-25, it is obvious that'the base may quiteas readily beemployed with the over feed type of ironer. In that case the pedestal l2-for the roll is mounted at 88, while the pedestal 9 for the shoe ismounted at 89 and is adjustable relative to the roll, in substantiallythe same manner as'previously described with reference to the adjustmentof the roll to the shoe.

A. feature of inyconstruction, both with the under feed and over feedtype of ironer, is the great amount of clearance between the lowermostelement'of the cooperating members (the shoe in the case of the underfeed ironer, and the rollin-the case of the over. feed'type) and the topsurface of the base. To this end the base 1 is cut away and ispreferably sloped downWard-. ly wherever possible, as at 150 (Figs. 15and 16), thus permitting great facility in handling the garments. y

A modified form of the arrangement whereby the roll is moved bodilyunder the actuation of the motor towards andaway. from the shoe, isillustrated in Figs. 10 and 11 in which 10 is a view from the exteriorof the modied construction, while Fig. 11 is a view of the `interiorsurface thereof. In the. end plate 104 shown therein; an angularly'arranged, straight slot A105 115;-

larm .104. Bearings 108and 109 are struck up from the interior surfaceof thev arm 104, and carried in the bearing 108 is a stub 110 on whichone bearing 6l' of the .pawl-plate 59' is mounted.

Theother two bearings 6 1', 61'l of the pawl-plate are mounted on asuitable shaft 111 carried in the lug or bearing 109. The collar 73with'its projecting lug 74 is the equivalent of the correspondingelements illustrated in Figs. 2- and 2l, a's is the cam 64.' A coiledspring 65 is provided for retaining'theJpawl-plate 59? with its c'am orpawl 5'1"'4 in vengagement with the cooperating teeth 56, while.theopposite extremity of the cam 57" is shown as terminating in anoutwardly,l

extending portion. 69 adapted to be engaged by -the eccentric strap 112,,fixed in any suitable manner vto the shaft 15". Movementof the rollrelativeto the eccentric strap, as a result of the; interlockingof theteeth 56 `and the cam 57, will cause engagement of the underside.' ofthe the pawl-'plate 59 will be swung' about its bearings 61' todisengage'the roll-locking means. It is believed'that this constructionwill be obvious, when considered with the'description of the prelferredform of my invention; t Still another exempliiication of that portion.of e niy invention pertaining -tjo .moving oneor `the v'projection-59with the eccentric 112, whereby .A 1,978,052 other of the roll and theshoe relative to the othervironer is illustrated. At 151 in thesefigures is shown a roll supporting arm corresponding to the arm 4 ofFigs. 1 and 6 and the arm 120 of Fig.12. On the interior face of the arm15.1 a guide -way is. provided by means of guides or tracks 152 and 153.The track 153 extends substantially entirely across the arm, while thetrack 152 extends -over only approximately half` of the width, for apurpose to be more fully described hereinafter. The knuckle joint whichrides in the rails, and which forms an essential feature of theexem'pllcation comprises, in the preferred form, an eccentric 154 havingan offset head portion 155 at one end in theI form of a split nut,adapted to be clamped around the means of an eye, about a bearing pin162 jourin the guides 152 and 153. Being restrained by such guides intoa substantially rectilinear path, the shaft 15 pulls the eccentric 154andthe rocker arm V160 from their buckled position as shown in dottedlines-in Fig. ,29, which position is per- :mittedI by the termination ofthe rail 152 sub` stantially at the mid point of the arm 151, and inwhich position -the roll is 'shown in the righthand dotted circle 6 asbeing removed from the shoe, into the fully extended position; shown 1nfull lines in Fig. 29, and in Fig. 30. When the eccentric and the rockerarm are in theirex-f 4tended position, the roll assumes the positionshown in the ,left-hand dot and dash circle of Fig. 29, and positivelyabuts' the shoe of the ironer.

My invention includes also means for hanging the ironer out ofthe way atsuch times when it is not in use. Any suitable means may be employedl tothis end, but experience Ahas shown that the simplest construction is toarrange an aperture 113 in the base member 1, adjacent theperipherythereof (see Fig. 16) A specially designed wall-bracket 114 (see' Fig.20) is adapted to cooperate therewith, and this latter may besecured tothe wall in any suitable manner as by screws 115. As better shown inFig. 20, this wall bracket has a substantially right-angular extension116, terminating in a knob 117, which latter prevents the ironer afterthe base member has been seated thereon, from being accidentally'disengaged from the bracket, as a result ofshock, or the like. It willof course be understood 'that the r aperture 113 is so placed, andtheironer 1 is so hung thereon, that the center of gravity ofthecompletedevice will be below the aperture, thus stabilizing its equilibriumposition on the hook.

A modified form of my invention is illustrated in Figs. 12 lthrough `19inclusive and 26, where-- in an under feed type of roller is employed.In this device, the arrangement is` much similar to that'of the overfeed type except vthat on the 80 roll supporting pedestal 2', a tubularshaft 118 is Sflxed, and at the extremities of this shaft arms 119 and120 are xedly mounted, each of these arms acting as a'support fortheroll 6. In this constructional form the pedestal 2v is'arranged 85substantially midway along the shaft 118 in the rear left corner of thebase 1, while the pedestal 121 for theshoe is arranged at the extremityof the shoe in the forward right-hand cor'ner of the base 1. I Theprovision of a support for the shoe at and .underone end thereof has thefollowing advantages. First, it is possible to use substantially all ofthe length of the -shoe for ironing sleeves or A other tubular fabrics,instead of only half the length of the shoe as would be the casev if theshoe were supported at -its midpoint. Second, where a flat fabric widerthan the shoe has been ironed bypassing between tlie roll and the shoe'and it is desired vto remove it from the base to- 100 vthe roll, bysimple reversal of the motor, and in the structural features to`behereinafter described.

As shown -in Figures 18 and 19, the arm 119 carriesbrackets 122 and 123in which is mounty Aed a shaft 124. On` this shaft is carriedby-suitable means such as bearings 125 and`126; a;

modified form of pawl-plate 127. 0n its underlface, as s hown in Figs.17 and 18, this pawl-plate carries a cam lug 128, adapted to cooperatewith the teeth 56 shown in Fig. 13. On its exterior 12.0

face, as perhaps best illustrated in Fig. 19, the pawl-plate 127 carriesa projection 129 having a reverse -bend therein for the reception 'of aneccentric l130. The eccentric is-shown. as hav- 'ing an aperture 131 forthe reception of theshaft 125 15 of the roll.

A spring 132 on -the yshaft 124 between mem-v bers 122 and 125 forms a.resilient connection between the turning shaft 124 and pawl-plate 127.A connecting rod 133 is pivotally connected 130 betweenboth member 74and a bell crank 134, which latter is pivotally mounted at the lower endof arm 119 (seelFigs. 18 and 19) A connecting rod 135 extends betweenmember .134 and a crank arm 136 pivotally mounted on base' 1 (see Fig.13), which latter'has a square opening to receive a correspondinglyshaped rod 137 of a knee control lever 138 (see Figs. 12 and 13). Areturn or torsion spring139 is locatedbetween members and 119 and hasits respective ends 140 anchored thereto. Eccentric arm 130 has rigidlysecured thereto one end of a stub shaft 140, whose other end has atuniing- 'movement in a sleeve 141 xed in arm 119 see Fig.'17).V

' A work board 142 is provided, at each end 145' thereof, with resilienthooks 143 ,whose outer endsiit into suitable sockets on the shoe, sothat thevboard 142 may be easily and quickly mount- I have intentionallydesigned the work board to '115,be' of an easily detachable type, thesupports yas mounting. Braces 144 have one end secured to* the bottom ofthe work board and have a portion extending along the back of the shoe,the

end of each brace engaging the back of the shoe.y

Thus the external surface of the .shoe is substantially smooth, and thelateral dimensions are such as to permit of easily and quickly locatinga sleeve'thereon to iron the same, the longitudinal lines of the-shoebeing smooth and what may be called stream lines, l

Since in the ironing of many types of garments I have found that; theuse of the work table is unnecessary and in-some instances undesirable,

of which will in no way interfere with the openness'of the shoe.

Means for carrying the ironer are shown as comprising a handle 145,preferably arranged on the arm 120, and this handle and arm are bestillustrated in-their cooperable position in Figures 14- an'd- 26. Theconstruction is vsuch that' the arm 119 will permitof the ironer beingraised onits end, in which position the handle, ,145 may be readilyseized for transporting .the same.

Itis obvious vthat at s'uch times the work board sleeve about the shoe,as the case nay be, the shoe is illustrated as terminating in a roundedend 165 of relatively large radius or radii of curvature, together witha slightly rounded end portion l166 as indicated by the dotted lines inFig. 27.

`Yet another feature of my invention is distinctly set forth in Fig..28, wherein is illustrated a cross section of the shoe according to my'invention.

Asfully set forth in other parts of the speciiication, itis a verydistinct purpose of my .invention to reduce the total weight of theironer. to a' minimum.- As is well known, however, it is essential thatthe shoe be of suicient mass that it will act in a sense'as a reservoirof heat, the iiow of which tothe garments to be pressed is retarded orregulated so that should a largewet garment be placed on the shoe,`theeffective temperature of the shoes surface would not be undulydiminished. In order to prevent these two essential -.features frombeing inconsistent,"as would at first glance appear to be the case, Iuse the construe.- tion'illustrated in 28. A central core 167, formed ofmaterial of high specific heat, yet light in `weight, suchfor instance,.as aluminum, is

' shown ashaving rearwardly extending bolt receiving projections or lugs168, 168'. Disposed closely adjacent to the core member, andimmediatelyto the' rear thereof is shown any conventionaltype of heatingelement 169 adapted to supply the necessary heat to the core, whichlatter member as will be more fully described hereinwaiter, acts las'the heat reservoir. In orderto properly seal as much as possible therear of the shoe against the loss of heat, a covering of heat insulatingmaterial is providdin the formof sheet asbestos 170, although an airspace of minute width is also effective. The front face of the core 167is preferably recessed as at 171, and this recess in the preferred formis iilled with suitable heat insulating material such as asbestos during-the ironing process. while referred to as preferably being comprised ofwool or the like l172. This last-mentioned means y servesthe functionofretarding'to a certain vextent the emission or 'conduction of heat .fromthe core member, the emission, as a consequence, depending mainly onradiation. A thin face plate of vsheet steel is illustrated at 173as'iltting snugly 'against the'shoe and -serving as the surface againstwhich the garment to be ironed rests This member 173,

stainless steel, may of course be Amade ofr'any other suitable metal andin the present instance vis shown vas fitting around the longitudinalends `found in practice that when the shoe oriron isl made thin and isformed of a solid metal, it is very diiiicult to regulatethe heat insuch manner as to minimize the danger of scorchingV the clothes.However, by myinvention the possibility of scorching is greatlydiminished, and almost entirely eliminated. This is accomplished byusing two metal pieces, one for the core and one for the face,l andproperly insulating the two members. This may be accomplished by anysuitable meansgsuch as ani air space necessarily incidental to lightcontact between. the metal pieces, or'bythe use of known insulatingmaterials.

As pointed out before, in an ironer'fo'r use on tables of varying heightit is important to obtain a sufficient amount of clearance between -theunderside of the shoe on the under feed type or' the roll onthe overfeed type, and the base of the machine, to .permit .the ready removal ofthe clothes therefrom, in order to preventA mussing of the garments, andto eliminate the possibility of burning the'hand of the operator. Themeans for accomplishing this have bee'ndescribed in detail previouslyinthe specification. However the shortness of .base 1, as seen in Figs. 6and 12, should not be ignored, inasmuch as it-is an important factor. 7

The base piece extends horizontally through the plane of the center ofgravity of the assembly but extends only far enough to steady themachine. Bly stopping atsuch point, it provides an extra -inch or so ofspace right at the point where the1 clothes are withdrawn by the lefthand of the operator. v

To permit ironing without fatigue to the operator when a portable typeof ironer is emby conserving 'the space between the shoe and the base.

When the roll moves toward'the shoe it will Aengage the latter at an'edge distant from that edge near which the roll will engage-the shoewhen ironing. Thus in Fig. 13 the roll will initially vengage the shoe10 at its lower edge and will then move upwardly thereon to a positionshown clearly in Fig. 26 where the roll engages the shoe adjacent totheupperedge of the latter. 'I'he roll rotates in a direction so. thatthe frictional forces between' the roll and the shoe tend to movetheroll into its final position, that is, the

position` occupied by the roll relatively to the shoe during ironing. Itis to be noted also lthat after the roll has'enga-ged the shoe-following its approach thereto, the resultant of the frictional forcesdue to the revolving of the roll under pressure against the shoe, willtend to advance the roll into Igreater pressure contact. It has beenpreviously proposed to move the ironertowards the shoe by swingablymoving the roll and its sup- 1,978,052 porting arms relative to the shoeabout a pivot external to the' roll and on the side thereof opposite tothe shoe. 'I'his construction however is not of such nature thatadvantage can be taken of the frictional forces of rotation. l

It is believed that the operation of thedevice has been fully developedfrom the foregoing. To summarize, the main featuresn of novelty of myinvention areresident in: f

1. The combination foot and knee control;

2. The motor and gear housing;

3. The general arrangement, wherebythe roll.

A is open at both ends;

' while the other member isrotatably mounted in 4. A means whereby theironer may be hung up out of the way when not in use;

5. 'I'he method of padding the roll; 6. 4The novel form of detachabletable for the under feed'type of roll; y

'1. The mechanism whereby the roll may be adjusted relative to the shoe;

8. The design of the base;

9. The novel form of the shoe, rounded at at least one'end and fdrming asleeve board:

10. The design and construction of the shoe, and

11. The means for and method of V increasing the pressure between theroll and the shoe as a result of the rotation of the roll whilecontacting against the shoe.
